LG 450W Mono X Plus Solar Panel – Ex-Demo | Premium Fixed Solar Panel

“Brand new, ex-demo, some dirt and dust on the bottom of the panels from storage.”

Premium Solar Performance from a Trusted Brand

LG earned a strong reputation for manufacturing high-quality solar panels with excellent efficiency, long-term reliability and strict quality control.

Although LG has since exited solar panel manufacturing, its Mono X Plus range remains highly regarded for its build quality and performance.

This ex-demo panel offers an opportunity to purchase a premium LG solar panel at a significantly lower price than a comparable new premium module.

✔ Ideal for caravans and RVs with limited mounting area

✔ Reduced mounting hardware in some installations

✔ Premium LG solar panel

✔ 450W high-output monocrystalline module

✔ High-efficiency design

✔ Positive power tolerance

✔ Suitable for fixed installations

✔ Australian stock

✔ Fast dispatch

What does "ex-demo" mean?

This panel has previously been used as a display or demonstration unit. Refer to the product description for details of its condition, any cosmetic marks and the warranty provided. Comes with a full 10 year warranty

Is this suitable for caravans?

Yes. Its high power output makes it well suited to caravans, motorhomes and other off-grid installations, provided your mounting area, solar regulator and electrical system are compatible.

Can I replace an existing LG panel with this one?

Potentially. If you're expanding or repairing an existing array, check the panel's voltage, current and dimensions to ensure compatibility with your existing system and inverter or charge controller.

Is this a monocrystalline solar panel?

Yes. The LG Mono X Plus uses high-efficiency monocrystalline cells designed for strong performance and efficient energy generation.

What size is the panel?

The LG 450S2W-U6 measures approximately 2115 × 1052 × 40 mm and weighs around 22.3 kg.
